[Orgmode] org-babel-R and windows ?

[d . tchin]

I need help to be able to use org-babel functionality. 
I use emacs 22.3.1 in windows XP and org-mode 6.34.

I have the following instructions in .emacs

(require 'org-install)
(require 'org-plot)
(require 'org-babel-init)  
(require 'org-babel-R)         ;; requires R and ess-mode
(require 'org-babel-python)    ;; requires python, and python-mode
(require 'org-babel-ditaa)

ESS module is loaded before :

(load "~/emacs/emacs-22.3/site-lisp/ess-5.7.1/lisp/ess-site")


I don't manage to get any output with R Software. 

Below you will find test I have done :

#+srcname:trial
#+begin_src sh
  echo output
#+end_src

#+results: trial
: output

#+srcname:trial
#+begin_src R
  c(4,5,6,7,8,9)
#+end_src


I manage to have shell output, but when I tried R procedure,
I have the following output in *Messages* buffer

executing R source code block...
Syntaxe du nom de fichier, de répertoire ou de volume incorrecte.
Source block produced no output

I have a look on temporary directory and I have the folllowing
file :

R-in-functional-results4452lyl

Inside the following source code :

main <- function ()
{

c(4,5,6,7,8,9)


}
write.table(main(), file="c:/Temp/emacs/tmp/R-out-functional-results4452y8r", 
sep="\t", na="nil",row.names=FALSE, col.names=FALSE, quote=FALSE)


The file  R-out-functional-results4452y8r exists but is empty.
What I miss to make it work ?
